Generally Tony, its pure cuss & cry, with the occasional wrecked part or broken $15 chip. I am with you, we need a gauge we can use with ANY tool simple by placing it and clicking "Home all", and my design is not it. Its a step in the right direction, but why the heck should I have to shut down LCNC and restart it with a different ini file that searches x for contact when switching to a thread cutting boring bar? Seriously guys, this is another user itch that ought to be scratched. Hell, just another button for x homing dir would help, a lot. Label it XHD+ or XHD- so you know which mode is in effect before you hit it with the mouse. Configure so it switches the homing dir -=moving for inward, +=backing out contact search.
